As a commercial airline pilot, Tyrone Nanton spends his days in a standard blue-and-white uniform. But in his off-hours, Tyrone’s creativity emerges in two favorite hobbies: creating colorful, elaborate costumes for carnival in his native Antigua, and painting. From 2006 to 2015, though, a tremor that got progressively worse made his hands shake so much that it kept him not only from those artistic pursuits, it eventually kept him from flying.

When the tremor started, Tyrone went to see a neurologist near his home in Brandon, Florida. To control the shaking, he was given a medication typically used for seizures. Due to regulations, however, the airline barred use of that medication. Tyrone had to find a different drug to manage his symptoms. Over time, however, even with an ever-increasing dosage of that medication, his tremor worsened.
